An unmissable milestone for fans of Sir Terry Pratchett: the first SF novel in over three decades in which the visionary inventor of Discworld has created a new universe of tantalizing possibilities--a series of parallel "Earths" with doorways leading to adventure, intrigue, excitement, and an escape into the furthest reaches of the imagination.

The Long Earth, written with award-winning novelist Stephen Baxter, author of Stone Spring, Ark, and Floodwill, captivate science fiction fans of all stripes, readers of Kurt Vonnegut, Douglas Adams, and Carl Hiaasen, and anyone who enjoyed the Terry Pratchett/Neil Gaiman collaboration Good Omens.

The Long Earth is an adventure of the highest order--and an unforgettable read.

1916: The Western Front. Private Percy Blakeney wakes up. He is lying on fresh spring grass. He can hear birdsong and the wind in the leaves. Where have the mud, blood, and blasted landscape of no-man's-land gone? For that matter, where has Percy gone? 2015: Madison, Wisconsin. Police officer Monica Jansson is exploring the burned-out home of a reclusive--some say mad, others allege dangerous--scientist who seems to have vanished. Sifting through the wreckage, Jansson find a curious gadget: a box containing some rudimentary wiring, a three-way switch, and a potato. It is the prototype of an invention that will change the way humankind views the world forever. The "stepper" enables a person using it to step sideways into another America, another wherever that person happened to be, another Earth. And if the person using it keeps on stepping, they keep on entering even more Earths. This is the Long Earth. And the further away a stepper travels, the stranger -- and sometimes more dangerous -- the Earths become.
